Specification of Letters Patent.

Patented Nov. 11,1913.

Application filed July 3, 1912. Serial No. 707,637.

To all whom it may concern Be it known that I, VIo'ron .MQ SUMMA,residing at .St. Louis,Missouri, and being a citizen of the Unitedcertain new and useful Improvements 1n Car-Door-Operating Devices, (CaseA,) of which the following is a full, clear, and or;- act description,such as will enable others skilled in the artto which it appertainstomake and to use the same, reference being had to the accompanyingdrawings, which illustrate the preferred form of the inven tion, thoughit is to be understood that the details obvious that variousmodifications thereof will occur to persons skilled in the art.

In said drawings: Figure 1 is a transverse sectional view taken on line1, 1 of Fig. 2; that is, taken transversely through a car longitudinalsectional view section beingtaken on line 2, 2 of Fig. 1.

The object of the invention is to provide doors, which will positivelylift and will their closed position, and which will unlock andpositively release the doors when they are in their closed position.

Referring to the parts; F indicates a center sill or central girder,which may be of any approved type of construction.

H represents generally a cross-bearing member commonly incident to carunderiirame constructions, which is connected with the :center sill bymeans of rivets G, passing through the flanges otthe members H andthrough the webs oifthecenter sill.

I is abottom wtie plate connected withthe idiaphragms H {and extendingbelow :the cone ter sill.

B B indicate angles which are commonly States, have invented 1described, as it is and Fig. 2 is a 01 the car, the

"lifting and locking and re leasing device, adapted to be applied to thehinged doors of dumping commonly known a as general service cars, theprincipal object being to arable and eliicient means for operating thecars, of .the class provide simple, du-

lifted to a oft-he brackets 1, within which are slidably mounted lockingbars l. bars are preferably formed These locking each of a single piecebent back upon itself, as shown in Fig. 1, to form loops 5, and are ofsuflicient length to project be end the outer edges of the doors to formlocking bolts 6, which locking bolts are adapted to pass through loopsin the hangers 7 which hangers are :secured in position by beingprojected through the horizontal flanges oil .the angles B, beforereferred to, and held n positlon by nuts 8 on the upper ends of saidloops 7. Connected with the cross-bearers H, in

any preferred manner, are bearings 9,which form seats for the-crank arms10 of shafts 11, which shafts are rockable in the bearings 9 and withinthe loops 5, before referred to.

Assuming the door S to be open, as shown at the right-hand SldQzOf Fig.1, the shaft 11 as indiis rocked in a clock-wise direction,

icatcd by the dotted l1ne and arrow 111 Fig.

1. This rocking ol the shaft 11 will cause retraetionof the bolt 6through engagement ofthe loop 5 with said shaft until the-door reaches ahorizontal position, at which time continued rotation of the samedirection Will cause the bolt 6 shaft 11 in the to be projected beyond.the outer edge of the door and into engagement with the loop 7, beforereferred to, and at the same time the shaft 11 is relieved from theweightoi the door and the door is supported by locking bar 6 engagingwith the loop 7 When it is desired to open the door, the shaft 11 isrocked in an opposite direction, the shaft cooperating with the loop 5to retract the bolt 6, thereby permitting the door to drop by gravity,but if, for any reason, tie door should stick and refuse to drop bygravity, the interengagement of the shaft 11 and loop 5 will cause thedoor to be pulled downwardly, so as to break any seal (such as an iceseal) which may have been formed.

It is to be observed that the doors S are not pivoted to the center sillor center girder F, but are supported upon brackets 15, which areriveted directly to the web of the center sill, and are so proportionedwith relation to the top flange 16 of the center sill that the inneredges of the doors in closing will be carried some little distance belowsaid top flanges 16, thus dispensing with the usual sill cover plate,which is common in car constructions of this type.

It is to be observed that the forward eX- tension 5 of the loop 5 willabut the rear inner edge of the bracket 1 when the bolt 6 is fullyprojected, thereby preventing rotation of the shaft 11, which rotation,if permitted, would allow the door to drop.

What I claim is 1. In a car, in combination with the frame of a car, apivoted door, a shaft pivotally mounted adjacent the door bearingagainst and supporting said door and sliding mechanism carried by saiddoor, whereby said shaft revolving in opposite directions, moves thedoor in opposite directions.

2. In a dumpin car, the combination of a side tension angle having adoor supporting loop secured thereto, a pivoted door, a bracket fastenedto the underside of said door, a locking bar slidably mounted in saidbracket, and adapted to be projected beyond the adjacent end of the doorinto said loop, and a rockable shaft in constant engagement with theloop.

3. In a. dumping car, the combination of a side tension angle having aloop secured thereto, a pivoted door, a bracket fastened to said door, alocking bar slidably mounted in said bracket, and adapted to project beyond the adjacent end of the door into said loop and means beneath saiddoor to actuate said locking bar.

4. In a dumping car, the combination of a side tension angle having aloop secured thereto, a pivoted door, a bracket fastened to said door, alocking bar slidably mounted in said bracket, and adapted to projectbeyond the adjacent end of the door into said loop and a swinging shaftactuating said locking bar.

5. In a dumping car, a hinged slidable bolt having an outer edge toproject from an edge of said having the inner end bent into a door, aadapted door and loop and door actuating means engaging said loopthereby to actuate the bolt.

6. In a dumping car having a holding loop, a hinged door, a bolt carriedby said door, means positively actuating said door in both directions,said means connected to said bolt to project the same into and from saidloop.

7. In a dumping oar having a holding loop, a hinged door, a bolt carriedby said door, means positively actuating said door in both directions,said means connected to said bolt to project the same into and from saidloop, and means limiting the outward movement of said bolt.

8. In a dumping car, a door hinged along one edge, a locking meanscarried by said door adjacent the opposite edge, door actuating meansmoving in an arc in a plane at right angles to said hinged edge andengaging the underside of the door, said means directly connected tosaid locking means to actuate the same.

9. In a dumping car, a door, a rocking shaft movable in an upwarddirection and directly supporting said door and door looking mechanismcarried by said door and actuated by the outward movement of said shaft.

10. In a dumping car, a door, a rocking shaft movable in an upwarddirection and directly supporting said door and door locking mechanismcarried by said door, said locking mechanism constituting the means forpositively lowering said door.

11. In a dumping car, a hinged door, locking means carried by said door,a rocking shaft movable in an upward direction to actuate the door andan outward movement of said shaft actuating the locking means.

12. In a dumping car, a hinged door, looking means carried by said door,a rocking shaft movable in an upward direction, the said movement ofsaid shaft actuating the door and an outward movement of said shaftactuating the locking means, and means limiting the rocking of saidshaft.

13. In a dumping car, a hinged door, a bolt carried by said door and acrank shaft directly engaging said bolt to actuate the same.

14. In a car door mechanism comprising a crank shaft adapted positivelyto actuate the door to open and close the same, and a locking meanscontinuously actuated by the movement of said shaft.

15. In a dumping car, a hinged door, a crank shaft supporting said doorand means directly connected to said shaft for locking and unlockingsaid door.

16. In a dumping car, a hinged door, a crank shaft supporting said doorin all of its positions and longitudinally slidable locking meanscarried by the door loosely engaged by said shaft to open and close saiddoor.

17. In a dumping car, a hinged door, a locking means carried by the doorand a crank arm connected to said means and adapted to positively lowerthe door.

18. In a dumping car, a hinged door and 1 a two-part mechanismconstituting pivot In Witness whereof I have hereunto set my hand 1n thepresence of two wltnesses.
